FMRI Studies of Visual Categorization in The Human Brain
Alexander Huth, et.al., at the University of California, Berkeley, have demonstrated how five human subjects, each viewing over two hours of movie clips, were each scanned by functional Magnetic Resonance Imaging instruments. Each brain scan recorded blood flow in thousands of individual locations, across their respective brains. Principal components analysis of regularized linear regressions revealed 1700 visual categories of 30,000 locations in cortex. Huth et.al. found highly organized, overlapping maps that occupied over 20% of cortex.

Famous quotes containing the words studies, visual, human and/or brain:
“These studies which stimulate the young, divert the old, are an ornament in prosperity and a refuge and comfort in adversity; they delight us at home, are no impediment in public life, keep us company at night, in our travels, and whenever we retire to the country.”
—Marcus Tullius Cicero (106–43 B.C.)
“For women ... bras, panties, bathing suits, and other stereotypical gear are visual reminders of a commercial, idealized feminine image that our real and diverse female bodies can’t possibly fit. Without these visual references, each individual woman’s body demands to be accepted on its own terms. We stop being comparatives. We begin to be unique.”
—Gloria Steinem (b. 1934)
“I set forth notions that are human and my own, simply as human notions considered in themselves, not as determined and decreed by heavenly ordinance.”
—Michel de Montaigne (1533–1592)
“When Western people train the mind, the focus is generally on the left hemisphere of the cortex, which is the portion of the brain that is concerned with words and numbers. We enhance the logical, bounded, linear functions of the mind. In the East, exercises of this sort are for the purpose of getting in tune with the unconscious—to get rid of boundaries, not to create them.”
—Edward T. Hall (b. 1914)
